LOUIS H. PETERS, OF BUFFALO, NEW YORK.

POCKET-KNIFE.

SPECIFICATION forming part of Letters Patent No. 279,794, dated June 19,1883,

Application filed January 539, 1883. (No model.) a

To aZZ whom, it may concern.-

Be it known that 1, Louis HERMANN PE- TERS, of Buffalo, in the county ofErie and State of New York, have invented certain new and usefulImprovements in Pocket-Knives, of which the following is aspecification.

This invention has reference to an improved pocket-knife of that classin which the knifeblade and the scales are adapted to swing around acommon pivot when opening or closing the knife, and in which the bladeis rigidly locked in open or closed position thereby.

The invention consists in a knife of peculiar construction, ashereinafter described and claimed, whereby economy, simplicity, anddurability are attained.

In the accompanying drawings, Figure 1 represents a side elevation of myimproved pocketknife, showing the scales spread apart. Fig.

2 is a side View of the same with the scales locked together and theupper portion of one of the scales broken away. Fig. 3 is an end view,partly in section; Fig. 4, a vertical transverse section on line m m,Fig. 2; and Fig. 5, a detail end view of the scales thrown in line witheach other, so as to show the abutments of the same.

Similar letters of reference indicate correresponding parts.

Referring to the drawings, a a represent the scales, which together formthe handle, and b is the blade of my improved pocket-knife. Both scalesa a are connected to the blade I; by a pivot-pin, (Z, which passesthrough the scales and the shank b of the blade I). The shank b of theblade I) is recessed at both sides and rounded off at its outer end, asshown clearly in Figs. 1 and 2. Each scale a and a is provided with aninwardly-project ing abutment, a", that fits accurately into one of theside recesses of the shank b of the blade. The abutments a are atdiagonally opposite sides of the scales, so that both fit into therecesses of the shank, and lock thereby the blade rigidly when in openor closed position.

The abutments a a are made half as thick as the shank b, so that theycan pass alongside of each other, as shown in Fig. 5, when the scalesare swung around the pivot-pin d for setting the blade. The outer endsof the scales o a are locked together, when they are placed one abovethe other, by means of a pin, e, and socket-hole e, the pin 6 beingapplied to a raised shoulder or check, e", of the scale a. When thescales (1 a are locked together the abutments a of the scales hold theshank b of the blade rigidly between them, as shown in Fig. 2.

For opening or closing the knife the scale a. is lifted clear of the pine, as shown in dotted lines in Fig. 3, after which both scales areturned around the pivot-pin d until they overlap each other again, andare locked together by the pin 6 and socket-hole e. The closing of theknife is performed in the same manner.

This construction is also specially adapted for surgical instruments ofall kinds, as the blades and their scales can be conveniently andthoroughly cleaned without difficulty.

In place of the knife-blade, any other implement may be substituted.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- As a new article of manufacture, a pocketknifeconsisting of scales a a, a blade, b, and a pivot-pin, d, uniting saidparts, the shank of the blade being proy ided with a rounded tang andshoulders on either edge thereof, and said scales being provided with alocking device, and with inwardly-projecting abutments a a, of half thedepth of the blade-shank, arranged diagonally opposite each other,substantially as described.

I11 testimony that I claim the foregoing as my invention I have signedmy name in presence of two subscribing witnesses.

. LOUIS HERMANN PETERS.
